Can you explain what that does and how it's a fix?

@Enkouyami: if some program can't find a lib there's a chance you can find it for her. In the above code the lib is found: /usr/lib/i386-linux-gnu/mesa/libGL.so.1. So now we have to notify playonlinux about it. The export line does it. I'm not sure it will work.
